Filed: 1956-11-29
Abstract: 810,994. Gain control of transistor receivers. GENERAL ELECTRIC CO. Ltd. Nov. 28, 1957 [Nov. 29, 1956], No. 36574/56. Class 40 (6). A superheterodyne sound radio receiver having a transistor intermediate-frequency amplifier, a diode or multi-electrode crystal second detector and automatic gain control which is effected on the intermediate-frequency amplifier, is provided with a manual gain control effected at a point prior to the second detector and to the point from which the automatic gain control signal is derived. The Figure shows an I.F. amplifier 1, second detector 10 and audio stage 22 of a superheterodyne sound radio receiver. An automatic gain control signal is derived from the collector of the second detector 10 and applied to the I.F. amplifier 1 and/or to preceding stages. Manual volume control is effected by a variable resistor 9 connected across the primary of the last I.F. output transformer 7. By this means it can be assured that the automatic gain control is effective on strong signals as well as weak. In addition the bandwidth of the receiver is increased for strong signals.

Title: Improvements in or relating to lock and associated electric control arrangements particularly for lifts
IPC: E05B65/00
Filed: 1934-12-22
Abstract: 449,401. Locking cage and well doors of lifts. FOTHERGILL, J. R., Brynteg, Fulthorpe Road, Norton-on-Tees, Co. Durham. Dec. 22, 1934, No. 36879. [Class 78 (iii)] [See also Group XXXVII] A lift cannot be started unless two sets of contacts are bridged independently by the closing of the door or gate, the one set being bridged by mechanical means associated with the gate-locking mechanism and the other by electromagnetic means mounted partly on'the gate and partly in the lock casing. In addition, a further locking-lever prevents displacement of the main locking - lever from the gate-locking position unless the cage is at the landing. The moving gate or door is fitted with a casing 2 carrying a pivoted latch 3, which is swung by a lever 4 to unlock the gate, and a permanent magnet 6. On closing the gate, the latch 3 enters the casing 9 on the post and automatically swings lever 10 clockwise about the pivot 11 to retain the latch 3, and also raises the rod 13 to bridge the contacts 15. At the same time the magnet 6 attracts the pivoted armature 17 and thus raises the rod 18 to bridge the contacts 20. The lift can then be started, but as soon as it leaves the floor a ramp on the cage releases the shaft 28 and so allows a spring 27 to depress the lever 26 and swing the lever 24 under the lever 10 against the action of the spring 25, thus holding the lever 10 in its gate-locking position until it is again released by the ramp on the cage. The magnet 6 is fitted with a rubber pad 8. A thin sheet 23 of suitable material prevents improper access to the armature 17. The two sets of contacts may be replaced by a single set, one contact of which is operated from the latch and the other from the armature, the contacts being brought into contact only when both members are operated.
Patent GB-1026693-A (GB)
Title: Improvements relating to polymers
Inventor: POPE GEORGE ARTHUR
IPC: C08G65/14
Filed: 1961-10-14
Abstract: The invention comprises polymers of propylene oxide, or copolymers containing up to 10 mole per cent of another epoxy compound, having a molecular weight of at least 2 x 106 and a minimum degree of stereo-regularity so that at least 25% by weight of said polymer or copolymer is insoluble in acetone at 0 DEG  C.  They are prepared by polymerizing propylene oxide alone or in the presence of a copolymerizable epoxidic monomer at up to 20 DEG  C., in presence of (1) a catalyst formed from a zinc dialkyl, e.g. zinc diethyl and water, the molar ratio of the zinc dialkyl to water being 1 : 0.9 to 1 : 1.05 and (2) a solvent for the propylene oxide, the amount of solvent to the total amount of monomer being at least 2: 1 and preferably up to 20: 1 by weight. The solvent is chemically inert to the catalyst and does not contain any active hydrogen.  Specified solvents are aliphatic, alicyclic and aromatic hydrocarbons, e.g. cyclohexane and benzene. Suitable copolymerizable compounds are butadiene monoxide, styrene oxide, cyclopentadiene monoxide, allyl glycidyl ether, phenyl glycidyl ether, cinnamoyl glycidyl ether, ethylene oxide, crotyl glycidyl ether and unsaturated epoxidic esters, e.g. glycidyl methacrylate and glycidyl acrylate. The catalyst is used in amounts of 2 to 5 mole per cent based on the propylene oxide. In practice, the zinc dialkyl is added to a dispersion of a known amount of water in the solvent and the monomers are added.  An inert atmosphere of nitrogen may be used or alternatively air or oxygen may be introduced into the polymerization system.  Any excess catalyst is subsequently deactivated by addition of a compound containing active hydrogen, e.g. an alcohol or steam. Polymers or copolymers containing at least 45% of stereo-regulated polymer are obtained by cooling a solution of the polymer to about 0 DEG  C. when the stereo-regulated fraction separates.  Polymers prepared as above may be vulcanized using sulphur or sulphur containing vulcanizing agents to provide materials used for making tyres, belting and shoe soles. Fillers, e.g. carbon black, antioxidants, extender oils and antiozonants may also be added prior to vulcanization.  The examples describe the copolymerization of propylene oxide and allyl glycidyl ether.
